To all whom it may concern:

Be it known that I, J OSEPH RAES, a citizen of the United States, residing at Schenectady, in the county of Schenectady and State of -New York, have invented new and useful Improvements in Portable-Wireless-Station Towers, of which the following is a specification.

This invention relates to collapsible towers adapted especially for use in a portable wireless telegraph station, the primary object being to provide means for extending the tower sections by the application of a suitvice of the class described which will, when its extensible parts are retracted, occupy a comparatively small amount of space so as to be readily moved from place to place.

Another object is the provision of means for strengthening and bracing the towensections when extended, said meansijbemg auto matically arranged in proper pgsition upon extension of the said sections.

The invention consists of the features of construction, combination and arrangement of parts, hereinafter fully described and claimed, reference being had to the accompanying drawings, in whiclia- Figure 1 is a fragmentaryside elevation of a portable station of the class described showing the towers inclosed elation with respect to each other, and tower sections retracted. Fig. 2 is a side elevation of the device showing the towers in separated posi- H011. and the tower sections in extended position. Fig. 3 is a front elevation of the front tower carried by the truck. Fig. 4 is a side elevation of the same. Fig. 5 a longitudinal sectional view taken on the -line 5-5 of Fig. 4. Fig. 6 is a transverse sectional view a side elevation of a modified form of tower.

gitudinal sectional view taken on the Fig. 9 is a transverse sectional view taken on the line 99 of Fig. 8. Fig. 10 is a 1online 10-10 of Fig. 9.-

Referring to the drawings, and in particular to Figs. 1 and 2, it will be seen-that I have provided a. motor vehicle or truck 1 which has a wireless station mounted therein and consisting of the necessary set of instruments 2. An extensible tower 3 is provided on the front part of the truck, its hollow rectangular base section 4 being fixedly secured thereto, as at 5. The other tower sections 6, 7 ,-8 and 8 are of similar cross section but are successively "smaller in diameter so as to be telescoped within each other, the section 6 being received within the section 4. The tower section 4 is provlded ad acent its upper end and at the front and rear sldeS thereof with a pair of bearing brackets 9 and 10. A vertical shaft 11 has its upper end rotatably mounted in the bracket 9 and its lower end rotatably mounted in a bracket 11 secured to the section 4 adjacent its lower end, and is supported by the beveled gear 13,-which latter is fixedly 1 secured to its upper end and is supported by the bracket 9. A rectangular shaft .12 is rotatably and slidably mounted in an opening provided in the bearing bracket 10 and has a beveled gear 14 loosely mounted upon the same above the bracket 10, its rectangular opening receiving the said shaft and it being supported by the said bracket. A horizontal shaft 17 is rotatably mounted in a pair of spaced bearing brackets 18 attached to the side face of the section 4 and adjacent its upper end, and has the beveled gears 15 and 16 fixedly secured to its opposite ends and adapted for engagement with the gears 13 and 14, respectively. A pinion 19 attached to the shaft 17 between the brackets 18 works through the slot 20 provided in the side walls of the said section 4 and is engageable with the vertically dis-' posed toothed rack 21 provided on the cor-- I responding face of the section 6. The rectangular shaft 12 extends upwardly from the bracket 10 through an opening in the bearing bracket 22, which projects laterally from the section 6, then through a beveled gear 23 supported by said bracket 22, still farther upward through a bearing bracket brackets 28 detachably secured to the section 6, intermeshes with the gear 23, so that upon rotation of the shaft 12, the toothed pinion 29, which is fixedly secured to the shaft 27 between the brackets 28, will be rotated in the slot 30 provided therefor in the section 6 and engaged with the vertically extending tooth'rack 31 provided in the side face of the section 7. A connecting shaft 32 is rotatably mounted in spaced bearing brackets 32 carried by the section 7 adjacent its upper end and on the opposite side thereof from the shaft 27. The said shaft 32 extends horizontally and has a beveled gear 33 attached to its forward end intermeshing with the supporting gear 25, and a beveled gear 34 fixed to its lowermost end intermeshing with a horizontally rotatable bev-. eled gear 35 which is supported by a laterally extending bearing bracket 36 attached to the section 7 opposite to the bracket 24, the said gear 35 being provided with a 'rectangular opening for the reception of the shaft 35, which latter is adapted to rotate the same. A pinion 32 carried by the shaft 32 extends through a slot 33 in the section 7 and engages the vertical rack 33 provided on the section 8. The shaft 35 is supported by a beveled gear 37, which is rigidly attached to its upper end and is supported by the laterally extending'bearing bracket 38 and carriedby the uppermost tower section 8. A horizontal shaft 39 mounted in spaced bearing brackets 40 carried by the said section '8 on the same side of the tower 'as the shaft 32, is provided at its outer end with a beveled gear 41, it intermeshes with the gear 37 and has a pinion 42 fixedly secured between the brackets 40 so as to engage the vertically extending rack 43 carried by the section 9 through the slot 44 provided in the upper portion of the section 8. A hydrocarbon engine, or some such, suitable source of power, (not shown) which furnishes the motive power .for the truck, is connected by means of a chain 45 with a sprocket wheel 46 carried by an operating sleeve or hollow shaft 47 mounted in suitable bearings within the truck body and beneath the floor 48 thereof. A longitudinally extending shaft 49 is connected at its innermost end by suitable clutch mechanism indicated by the numeral 50 with the said sleeve 47, and has its front or outermost end provided with a beveled gear 51 which intermeshes with a similar gear 52 secured to the projecting lower end of the shaft 11. It will thus be seen that when power isapplied to the shaft 49, the shaft 11 will be rotated, the shaft 12 will I be rotated likewise through the medium of the shaft 17, and the shaft 35 will also be rotated through the medium of the shaft 32,

causing rotation of the uppermost horizontal shaft 39. The rotation of the horizontal shafts will impart vertical movement to the movable tower sections through the medium of the racksand pinions provided therefor, so asto extend the said sections. A movable, supporting truck 53 carrying the rearmost tower 54 is provided with wheels 55- whose axle 56 is located above the plane of the axles 57 and 58 on the main body truck, which are supported by the wheels 59 and 60, so as not to interfere with the motion of the truck proper when the towers are in their closed position with respect to each other. A forwardly extending connecting pole 61 is attached to the truck 53 and has its forward portion slidably mounted within a telescopic member 62. The member 62 is telescopically received by a second member 63, which latter is also slidably mounted within a housing 64 provided within the truck body. I The movable truck 53 is adapted to be moved away from the vehicle body or truck proper so as to separate the tower 54 from the tower 3 by any suitable means therefor, a telescopic connection between the said movable truck and vehicle body just described being extended to the limit in this operation. A rotatable, operating sleeve 65 is mounted in suitable bearings within the vehicle or truck body and is connected in suitable manner to the prime mover. A shaft 66 is slidably mounted within the sleeve 65 and is held against rotation therein by some suitablemeans, such as a keyed slot, or it may be constructed rectangular in cross section to be received by the rectangular bore provided in the said sleeve. The outer end of the shaft 66 is connected by suitable gears to the mechanism for elevating the sections of the tower 54, which mechanism is identical with the previously described mechanism for opcrating the tower 3, thetower 54 being merely turned through an angle of 90 so as to slightly change the relative position of the parts of the mechanism carried with relation to the mechanism onthe tower 3. When the movable truck 53 is moved in its extended position, it is supported by a block 67 having grooves therein for the reception of the wheels 55. In this position of the movable truck, the shaft 66 has been moved outwardly through the sleeve 65 and is still adapted to be rotated by the prime mover when applied to the sleeve 65 through the medium of suitable clutch mechanism, not shown. The shafts 66 and 49 are adapted .to be operated by the said prime mover" so as to simultaneously extend the power section. When the towers are in their separated position and their extensible sections aerial 68 is located atthe suflicient height for a proper operation of the wireless station, the said aerial'being connected to the station instruments by means of the lead .wire 69. The high tension current for use in connection with the station is generated by means of a dynamo 70 which 1s connected with the prime mover or source of motives power for the vehicle by some suitable means which may be readilyregulated. V

= In Fig. 7 I have shown the upper end of each section of a collapsible tower provided with a plurality of laterally extending arms 71, whicharms project preferably from the sides of the section by which it is carried. A spring retracted drum 7 2 is attached to the outer end of said arm 71 and carries a bracing cable 73' whose outer end is attached to the inner portion of the arm'on the corres onding side of the tower section next a ove, as at 74. It will thus be seen thatwhen the sections are in closed or collapsed position, the cables 73 will be partially re tracted and will lie flat against the upper surface of their respective attaching arms. Upon extension of the tower sections, how+ ever, the cables will be extended to their 1 limits, and will efi'ectivelyjbrace the said sections, thus tending to resistlateral strains upon the tower due to heavy winds or the li e. a

In Figs. 8, 9 and 10, Ihave shown a modified form of tower which may be used in connection with my improved ortable station and which may be operate ,withoutthe use of shafts, gears, and such mechanism. The numeral 75 designates the hollow base section of the tower,"which is rectangular in cross section and shdably receives a second section ,7 6. A plurality of successively reduced, telescoping tower sections 77, 7 8, and 7 9 are provided. The section .75 is provided in opposite sides with outstruckportions 8O and 81, afl'ording the internal, longitudinal grooves 82 and 83, .respectively. The elevating cable 84 Wh10h is connected to some source of power, (not shown), such as a drum, passes over a pulley 85 attached *to the section 75 at its upper end, down through the groove 82, around a pulley 86 carried by the lower .end of the next section 76, then up- .wardly through the-groove 83 in the opposite side of the said section 75, then for- .wardly to the pulley 87 carried by the upper end of the 'section76, where it is turned downwardly through a longitudinal groove 88 provided in the outer face of the corre. sponding side of the section 77 by the instruckportion 89, around the pulley90 attached to the lower end of the section 77, up through the groove 91 provided in-the opposite side of the section 77 by the instruck portion 92v tothe pulley 93 carried by the upper end of the section .77. From here it maven passes down through the groove 94 provided in the corresponding side of the section 78 by the instruc'k portion 95, around the pulley 96 carried by-the lower end of the section 78, up through the groove 97 provided in the opposite side of the section 78 by the 'instruck portion 98. It then passes up over the pulley 99 carried by the upper end of the section 78 and downwardly through the groove 100 provided in the topmost section of attachment 102 with the lower end of the said section. Upon the application of power to the lower end of the cable 84, the tower sections will be drawn into their ele- .79 by the instruck portion 101- to its point:

vated, extended position by one continuous.

movement.

Itwill be seen that I have provided a portable wireless station which is adapted especially for use in military operations, or. the like, wherein it is desirable to have a number of wireless stations whose position may be changed at any time with as little consequent delay as possible.

A yery desirable feature of the station which I have invented is "the fa'ct that it may be operated bya very small number of men, nearly all of the operations being performed by the prime, mover of the vehicle itself.
